    Abstract: A optical fiber, for example a Dispersion Compensation (DC) fiber, for compensating dispersion of a transmission fiber (such as a NZDSF) and transmission line including same. The fiber has a refractive index profile having a first moat with a negative delta (Delta2), and a second moat with a negative delta (Delta4) wherein the fiber exhibits a negative total dispersion at 1550 nm, and kappa at 1550 nm of less than 75 nm. The DC fiber, when used in a transmission line, may provide low residual dispersion across the C band when such lines include transmission fibers with total dispersion between 2 and 6 ps/nm/km and dispersion slope less than 0.092 ps/nm /km at 1550 nm.

    Abstract: A higher order mode stripping optical fiber having a core surrounded and a cladding layer surrounded by a coupling coating having a higher refractive index than the higher order mode effective index and wherein the cladding-coating interface between the cladding and the coupling coating is located at a radius 1500 nm. Such fibers are particularly effective at attenuating unwanted higher order modes and are useful in Dispersion Compensating modules (DCM's). Modules and systems utilizing the higher order mode stripping fiber are also described.

    Abstract: dispersion and dispersion slope compensating optical fiber includes a segmented core and a cladding layer wherein the refractive index profile is selected to provide a dispersion having a maximum deviation of less than 7 ps/nm-km over a wavelength band from 1550 nm to 1610 nm. According to a further embodiment of the invention, a dispersion compensating optical fiber is provided having a refractive index profile with a central core segment having a positive relative refractive index; a depressed moat segment on a periphery of the central core segment having a relative refractive index that is more negative than -1.2%; and an annular ring segment outward from the depressed moat segment having a relative refractive index that is greater than 1.2%.
